BRUSH CONSTRUCTION.

Application filed February This invention relates to improvements inbrushes of the ordinary cleaning type, and particularly to the mountingof the bristles in their holders or supports.

The principal object of my invention s to secure the bristles so thatthey are positively and firmly held in place in the holders without theuse of glue or cementitious material of any kind being necessary. Eachset or row of bristles is mounted in an individual holder, anarrangement which of course provides a very narrow brush area.

A further object of the invention therefore is to provide means forreadily connecting as many holders together as may be necessary to forma brush of any desired width, in such a manner that the complete brushstructure will be very light compared with the area covered by thebristles so that the brush will be very easy to handle.

A further object of the invention is to produce a simple'and inexpensivedevice and yet one which will be exceedingly effective for the purposefor which it is designed.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views:

Fig. 1 is a perspective elevation of a brush formed with a singlebristle holder.

Fig. 2 is an enlarged cross section on the 0 line 22 of Fig. 1.

Fig. 3 is a perspective elevation of a brush bu lt up of a number ofholders spaced transversely relative to the plane of the handle.

Fig. 4 is a fragmentary enlarged cross section on the line lt of Fig. 3.

Fig. 5 is a perspective elevation of a brush built up of a number ofhandles, spaced longitudinally of each other relative to the plane ofthe handle.

Fig. 6 is a perspective view of a griddle greaser utilizing my improvedbristle mounting means.

Referring now more particularly to the characters of reference on thedrawings, the bristle holding feature of all the brushes is the same andcomprises a metal plate 1 of deep Ushaped cross section. The bristles 2are disposed between the sides of the plate from end to end thereof toform a row,

each bristle being also bent double in U-shaped form and of courseprojecting outwardly of the plate a certain distance, depending on thetype of the brush. The bristles are held in place by a wire 3 which isinserted between the two le s of each bristle member at the bendthereof, and after this is done the sides of the plate are pressedfirmly together beyond the wire, as indicated in Fig. 2. This of courseprevents movement of the wire from its location in the plate, andprevents the bristles from dropping out. Since this pressure when thusapplied to the plate also clamps the bristles between the wire and platesaid bristles cannot pull out. A brush thus constructed should thereforelast indefinitely, since the bristle holding means is of such a naturethat there is no tendency for it to rot or disintegrate, as is thetendency with the brushes in which the bristles are glued or similarlysecured in place. Manufacturing operations may also be much more quicklyand easily carried out.

Each holder with a complement of bristles and the wire 3 therein lendsitself readily for assembly with other holders to form brushes ofvarious sizes.

In Fig. l I have depicted a brush of a narrow type, suitable for certainuses and utilizing a single holder and a corresponding number ofbristles. In this type the plate member 1 is merely extended beyond thebristle holding area to form a handle 4: of any desired length.

In Fig. 3 I show a brush of typical clothes-brush form, and in Fig. 5 abrush of the sweeping type. To connect the requisite number of holderstogether in either type I merely extend the wires 3 beyond the holders acertain distance at both ends, as shown at 5 in Fig. l. These extensionsare then inserted and clamped between the sides of cross plates 6similar in form to the holder plate 1, and the wire extensions then bentdown so that the plates 6 rest vertically across all the holders attheir ends, as shown in Figs. 3 and 5. The various parts may then itnecessary be soldered together at various points to prevent the movementof the holders relative to each other and to hold the cross platesagainst movement relative to the wires clamped therein and to theholders as well. A wire handle 7 of suitable type to extendlongitudinally of the holders may be Ill) readily connected by solder orthe like to certain ones of the holders in the type of brush shown inFig. 3.

In the type of brush shown in Fig. 5 a number of wires 8 preferablyconverge toward each other from various points on the outer bristlehandles to form a handle 9 extending in upward direction and at asuitable angle. This arrangement adequately braces the relatively largebristle holding structure to the handle.

In Fig. 6, I hare shown the bristle arrangement as applied to a griddlegreaser of the general type shown in my Patent No. 1,612,- 926 datedJanuary eth, 1927. This greaser comprises an inverted cup 10 having ahandle 11, with the plate member 1 holding short bristles 2 bent in theform of a ring to fit inside the cup.

From the foregoing description it will be readily seen that I haveproduced such a device as substantially i'ullills the objects of theinvention as set lorth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit 01"the invention, as defined by the appended claims.

Having thus t cscribed my invention what I claim as new and useful anddesire to secure by Letters-Patent is:

1. A brush comprising a plurality of spaced b 'stle holding members,wires projecting from the ends of said members, and means supporting andsecuring said wires at their ends to maintain the members in fixedspaced relation to each other.

2. A brush comprising a plurality of separate elongated bristle holdingmembers spaced apart, wires projecting from the ends of said members,and plate members of U-shaped cross section extending across the ends ofthe holders and between the sides of which the ends of said wires aresecured.

3. A brush comprising a plurality of separate and spaced holdingmembers, bristles projecting therefrom, plate members across the ends ofthe holding members, and a common means securing the bristles in theholding members and connecting the latter to the plate members.

In testimony whereof I afiix my signature.
